1. The problem statement, all variables and given/known data Implicit Differentiation:Use implicit differentiation to find an equation of the tangent line to the curve at the given point. x2/3 + y2/3 = 4 at (-3*31/2,1) 2. Relevant equations ??? None? 3. The attempt at a solution 2/3 * x-1/3 + 2/3y-1/3*y' = 0 then after a few steps of switching the sides of the variables y' = (-2x1/3)/ 2/3*y-1/3 The part that I'm just confused on is putting x into the variables, especially since we're not suppose to use calculators, any help?
